A barrier or frame to retain the grout
which will be later poured between the
pump base and the foundation must be
provided around the hole for the pump
column.
Some pumps are provided with a
sole plate that fits between the discharge
head and the foundation. In this case, the
foundation bolts must align with the
holes in the sole plate rather than those
in the discharge head. The sole plate is
normally installed with the pump, but
you may choose to install it beforehand.
Whether the sole plate is installed
prior to the pump installation or at the
same time, the discharge head must be
attached to the sole plate. Inspect the
bottom of the discharge head to verify
that it has been machined over its entire
surface and that it is clean and free of
burrs and nicks. The machined surface
of the sole plate is installed against the
machined surface of the discharge head.
Failure to have each component's
surface machined will result in excessive
vibration.
Follow the instructions on page 23
for leveling and page 24 for grouting.
After the grout is cured (a minimum of
48 hours), the discharge head may be
removed to start the pump installation.
Peerless Pump does not recommend
installation of the sole plate without the
discharge head; however, if there is no
choice except to install the sole plate
alone, use the machined surface at the
top of the sole plate (the discharge
mounting surface) for leveling. Due to
manufacturing tolerances, the levelness
of the assembled pump may vary from
that of the sole plate.
Be sure to position the foundation
and locate the foundation bolts so that
the discharge head will be in accurate
alignment with the discharge piping.
